Specification of Letters Patent.

Patented Apr. 29, M919..

Application led December ,16, 1916. Serial No.`137`,324.

j structed of two pieces of sheet metal drawn A t0 appropriate form and united by Hanging,

soldering or otherwise. The invention is particularly directed to a nut for use in connection with pneumatic tire valves, chiefly those which are used as rim nuts and which are provided with bushings attheir upper-ends, designed to receive a dust cap. Such nuts aret'best formed wi-th anl exterior shell which is usuallyhexagonal inl contour, and an interior lining piece having a recess which is vadapted toreceiv'e a leather or other washer which makes a contact with the rim of the wheel. Particular features of .the invention will be hereinafter more fully described.

Referring to the drawings which illustrate the preferred form of the invention,-

` Figurel is a crosssectional view of the rim showing the nut in elevation;

lFig. 2 is a diametricalsection of the nut; Fig. 3 is an underside view of the nut; Vllig. a is an elevation of the lining member detached. y p

Referring lirst to Fig. l, let t indicate the wheel rim or telly, B a pneumatic tire valve and C the nut as a whole. lin this construction the nut is formed with a screw-threaded projection or bushing which is designed to receive the dust cap. This feature may be omitted, andin fact, the. nut maybe conf,

structed as a washer if desired.

Referring now to Figs. 2, 3 and 1l, let C1 indicate the outer shell or body of the nut which'is formed of sheet metal. When the nut is to be provided with a bushing the shell vC1 may be constructed with a tubular extension D which may be externally screwthreaded as shown. For economy the gage y of metal employed is light and the interior recess formed on the shell or body G1 et the nut is too deep for a packing washer such as E which' is usually termed of leather. Hence, in'order to maintain: the washer in a suihciently extended position, a lining meniber iF is -employed which .is fitted in the renut, the lining -member is usually formed with a tubular extension Gr which is interiorly screw-threaded as shown. rlhe parts are commonly united by Hanging or riveting the internal extension over the external,.as indicated at H. 'The parts are preventedV from relative rotation by forming the lining member with a hexagonal shape vadapted to lit the internal shape of the body portion C.

To prevent axial movement of the lining member relatively 'to the body when the device is screwed on a valve shell, a series of lugs rl are provided which are bent back to engage the body member as shown. As formerly constructed, the entire metal was bent back in this direction in the form of a flange. lin the use of these devices the packing washer E is sometimes lost, oris compressed until the edge J of the nut body has contacted with the rim. When this occurs a further tightening of thenut forces 'the lining member still farther inward while theV 1 to. become destroyed so that the sections are parted. lln order to prevent this, instead oit turning back all of the metal, portions thereof such as the lugs ll are turned back, and portions are Vturned `forward as shown at lli. lhe forward faces L of these portions lie Hush with the face J., and when the latter contacts with the rim the faces L contact also so that the lining member cannot advance ahead of the body member when the nut is tightened, and the permanance or the connection H is thereby assured. lt is preferableto utilize a circular packing instead ot one which has a hexagonal contour, andin order to accommodate as large a packing as possible the lugs K are preferably located at the angles of the body portion, as best seen in l4`ig. 3. By so locating the lugs a circular packing washer of maximum diameter can be utilized; in other words, the provision or the lugs does not reduce the diameter of a packing which could otherwise be employed wit-h a hexagonal nut. This'is indicated in dotted lines in Fig. 3.

rlhe invention is applicable to other constructions than that described, such as sheet metal washers or the like, and within the scope of the appended claims the parte may rsL lll@

be lvaried without departing from the spirit of the invention.

What ll claim is having a body portion and an interior lining member connected yto the body portion by means, acting under normal conditions to prevent their relative axial movement, they lining member having parts extending to the forward face of the body portion.

2. A device of the character described having a body portion and an interior lining memiber connected with the body portion by means acting under lnormal conditions to prevent their relative axialmovement, having a washer seat spaced forwardly from the body portion, and said lining member having. parts extending forwardly to the front face of the body portion.

3. A device of the character described comprising a body portion and an interior lining member connected with the body portion \by means acting under normal condi-h tions to prevent their relative axial ino-vement, the latter having a washer seat/spaced forwardly from the body' portion and having lugs extending in reverse directions, one set contacting with the body portion and the other extending forwardly to the front face of the body portion. i

4. A device of the character described vcomprising a sheet metal body portion hav.-

vhaving a tu'bular extension, a lining portion having a tubular extension within the ex-v4 tension of the body portion and formed with a` screw thread, a connection betweenf said extensions to normally hold the parts together, and lugs on the lining portion extending forwardly to the fron-t face of 1. A device of the character described,

the body member.

6. A device of the character described comprising a. sheet metal body portion havingV a tubular extension, a lining portion having a tubular extension Within the extension ofthe body portion and .formed with a screw thread, a connection between said extensions to normally hold the parts together, and lugs on the liningV portion extending forwardly to the front face of the body member, and lugs extending rearf wardly to contact with the body member.

7. A device of' the character described comprising a sheet metal body member of polygonal form` and havingvan externally threaded tubular extension an internal lin# form having an' ing member of similar internally threaded tubular extension ararranged in the angles of the body member. y

8. A device of the character described comprising a sheet metal body member of polygonal formV and having an externally threaded tubular extension, an internal lining member of similar form having an internally threaded tubular extension arranged within the lirst, a connection bei tween said extensions, lugs formed on the lining member extending forwardly to the front face of the body member, said lugs arranged in the angles of the body member, and intermediate lugs extending rearwardly to the body member.
